Reading this thread, I had a sudden insight about what seems to frighten Mary and some others: that we're seeking really great strength, and they're associating that with great "muscular" strength and the kind of power that goes along with that. This gave me a sudden laugh because what we're seeking is not more muscular power, but the power to do more with less muscle! We want to be unaffected by an opponent's power while remaining completely relaxed and unexerted! We're not talking wild-man hell-raising burning-red eyes and uncontrolled frenzy. We're talking about calm, smiling, amused, relaxed, funny absorption of all power that comes against us, leaving us unexerted, unstrained and completely free to move no matter what kind of load comes upon us. When done properly, it feels like we're not doing anything at all, yet nothing can hold us back or divert us.

For those who find the pursuit of power worrisome, the kind of power you describe is at least as fraught with danger as the muscular kind, and probably more so.
